H EATING-STOVE.

SPECIFICATXON forming part of Letters Patent No. 348,218, dated August31, 1885.

Application filed March 5, 1886. Serial No. 194,088. (No model.)

To all wwm it may concern:

Be it known that I, JosIAI-r J EWETT, a citizen of the United States,residing in the city of Buffalo, in the county of Erie and State of NewYork, have invented a new and useful Improvementin Heating-Stoves, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in heating-stoves which have afre-cha1nber section, an ash-chamber section, and a base-section havingtherein a prostrate fire-due or re-ilues communicating with thefire-chamber by a descending flue or lues, and with an exit-passage forthe gases of combustion.

The general objects of my improvements are to increase the disengagementof heat from the lower portion of the stove, to decrease the heat of theouter side casing of the base-section and thereby lessen its liabilityto burn or seorch articles of clothing or personal wear brought againstor into contact with such outer side casing, and to induce a current orcurrents of air to rise from under the stove upward through and beheated in a iiue or iiues in the lateral side part or parts of thebasesection, and thence pass outward from the lower portion of the stoveinto the open air, and in proper position to permit persons seated bythe stove to conveniently warm their feet by such current or currents ofheated air, which will rapidly ascend and thereby promote thecirculation of the air in or throughout the apartment in which the stoveshall be used.

In the accompanying drawings, Figure l represents aside elevation,partly in section, oi' a portion of a stove which embodies one form ofmy invention. Fig. 2 shows a vertical section of the same in the planeof the line z z in Figs. l, 8, and 4, and an elevation of some parts inrear thereof, viewed in the direction pointed by the arrow fy. Fig. 3represents a horizontal section of the same stove at or about the line xin Figs. l and 2, with a plan of some parts below. Fig. 4 shows ahorizontal section at and a top view of some parts below the plane ofthe lines w w in Figs. l and 2.

Like parts are marked by like letters in the different figures, and thearrows therein indicate the direction in which the gases of combustionand the currents of heated air pass through the stove.

Prior to this invention some heating-stoves have had a fire-chambersection with an outer casing, a, fire-pot b, grate c, and flame-chamberA, an ash-chamber, B, under the {irechamber, and adapted to receive andcontain an ashpan, d, and having an outer casing, e, and sometimesfoot-rails G,`supported outside by brackets f, and a base-sectionfurnished with legs g, and occasionally with a down wardly-extendingborder-ski rting, D, and having between the bottom h of the ash-chamberand the bottom z' of the base-section a prostrate fire-Hue ortirc-iiues, E, extending throughout or along the side or sides of thebase-section, and having communication with the flamechamber by adescending flue, F, and with the exit-passage for the gases ofcombustion by an ascending flue, G, in the rear part of the stove. Suchstoves commonly have the outer lateral casings of the fire-flue orre-ilues in the base-section consist of the outer side casingsj, which,by contact therewith of the current or currents of highly-heated gasesof combustion in said base flue or iiues, usually become so hot as toburn or scorch articles of wearingapparel inadvertently brought incontact with said outer casings, and to burn or injure the feet, shoes,or stockings of persons attempting to warm the same by resting them uponor against the outer side casings of the base-section. To avoid thatdefect, and also increase the disengagement and discharge of heat fromthe base-sectionA in a current or currents of air, I make and arrange inthe base-section, between its outer casingj and the flreiiue or re-iluesE, the partition plate or plates k,and an air-fluel or air-ilues, H,having at the bottom an inlet passage or passages,l, to admit outsideair from under the base-seetion,and at the top an outlet passage orpassages to discharge into the open air from the lower portion of theside or sides of the stove the air that will be heated in passing upwardthrough said airilue or air-fines. Such discharge passage or passagesfor the heated air may be directly through and along the upper part ofthe outer side casingj of the base-section, as indicated by dotted linesat 'v in Figs. l, 2, and 3.

To increase the heat of the current or cur- IOO rents of air that willrise through the base flue or lues H, and economize the heat radiatedfrom the lower portion of the fire-pot and utilize the commonly vacantspace between the sides of the ash-pan d and the outside casing, e, ofthe ash-chamber section, I make and arrange in that section thepartition plate or plates m, and between the latter and the outer sidecasing e, an airflue or air-ilues, I, having at the bottom aninletpassage or passages, n, Figs. 2 and 3, from the ue or fines H,and alsohaving through any suitable part or parts of the outer casing e, butpreferably through and along its upper portion,an outlet passage orpassages, o, for the heated air that shall ascend through the flues Hand I.

To cause the outer air which shall be heated under and by contact withand radiation from the highly-heated bottom z' of the base-section torise through the flue or fines H orHand I, and be further heated thereinand discharged therefrom, as above specified, I have the border-skirtingD extend below the bottom all around the latter, and have the inletpassage or passage Z to the flue or ilues H within the circuit limits ofsaid border-skirting and above its lower edge, p, essentially asillustrated by Figs. 1, 2, and 4.

To cause the current or currents of heated air that shall rise throughthe flue or ilues H or H and I to issue from the stove in properposition to warm persons feet placed or resting on the foot-rail orfoot-rails C, I arrange the outlet or outlets for such current orcurrents under or below said foot-rail or foot-rails-as at v or o, forexample-so that the current or currents of heated air issuing thereatfrom the flue or ues H or H and I will pass under and rise past thefoot-rail 0r foot-rails in ascending along the outside ofthe stove toits top, and thereby promoting the circulation of the air throughout theroom in which the stove is used.

I claim as my inventionl. In a heating-stove, the combination,with itsbase-section having therein a fire-flue, E, of the air-heating sideflue, H, cased on its outer side by the outer side casing j of thebase-section and on its inner side by the outer side casing 7c of thelire-flue, and having at its bottom an inlet, Z, for the outer air, andat its top an outlet for the heated air into the open air at the lowerpart of the stove, substantially as shown and specified.

2. In a heating-stove, the combination,witl1 its ash-chamber section andbase-section having therein a lateral fire-flue, E, ofthe air-flue Hbetween and cased laterally by the outer side casing j of thebase-section and the outer side casing k of said fire-flue, and havingthe bottom inlet-passage, l, and the air iue or passage I between andcased laterally by the outer and inner side casings, e and m, of theash-chamber section, and having the bottom inlet-passage, n, from theHue H, and the outlet-passage o through the casing e, substantially asset forth.

3. In a heating-stove, the combination, with its base-section havingtherein a fire-flue and provided with the border-skirting D, extendingaround and below the bottomi of the basesection, of the air-heating sidefine, H, between and cased laterally by the outer side casing j of thebase-section and the outer side casing 7c of said fire-Hue, and having abottom inletpassage, Z, within the circuit or limits of saidbor'der-skirting and above its lower edge, and a top outlet-passage forthe heated air from the lower portion of the stove, substantially asshown and specified.

4. In a heating-stove, the combination, with its ash-chamber sectionfurnished with the footrail C, and the base-section having therein a{ire-flue, E, of the air-heating side flue, H, between and casedlaterally by the outer side casing 7c of said re-flue and the outer sidecasing j of the base-section, and having a bottom inlet-passage, Z, forthe outer air, and a top outlet-passage for the heated air under saidfoot-rail, as set forth.

5. In aheating-stove, the combination, with its ash-chamber sectionfurnished with the side foot-rail, C, and the base-section havingtherein a'fire-flue, E, and provided with the downwardly-extendingskirting D, of the airheating side ilue, H, between and cased laterallyby the outer side casing j of the basesection and the outer side casing7a of said fire-flue, and having a bottom inlet-passage, l, within thelimits of the border-skirting and above its lower edge, and the airpassage or flue I between and cased laterally by the outer and innerside casings, e and m, of the ashchamber section,and having theinlet-passage n from the flue H, and the lateral outlet-passage o belowsaid foot-rail, substantiallyas set forth.

In testimony whereof I hereunto set my hand, in the presence of twosubscribing witnesses, this 1st day of March, 1886.
